Apple, XML, and the Music Store: Thanks to Tim Bray, we now know that there is an XML interface to the Apple Music Store. In the search for more information to understand what was provided to us and what they were getting from users buying information, I checked inside the actual track XML. In this case, I picked an XML sample file from their site and dissected it. This is all very geeky so if you’re not interested in the Apple store or in XML, no need to read on.
